Title: Power transmission mechanism of metallic belt
Inventor: LEE JONG WAN
IPC: F16H61/662
Filed: 1999-07-13
Abstract: PROBLEM TO BE SOLVED: To efficiently transmit large motive power regardless of a transmission gear ratio by connecting a driving pulley and a driven pulley to each other by many thin metallic belt, and performing curvature motion by each metallic belt while rotating the pulleys with same angular speed. SOLUTION: When a driving shaft 11 is rotated by a power source, turning effort of the driving shaft 11 is transmitted to a driven shaft 19 through two metallic belts 27 which are wrapped between the driving pulley 17 composed of first and second driving pulley pieces 13, 15 freely to advance/retreat along an axial direction of the driven shaft 11, and the driven pulley 25 composed of first and second driven pulley pieces 21, 23 freely to advance/retreat along an axial direction of the driven shaft 19. Belt guide parts 14, 16; 22, 24 which are provided with an inner belt 45 and an external belt 47 and which are composed of an inclining part formed in a nearly recessed curve surface, are formed on each surface opposed to the pulley pieces of the driving pulley 17 and the driven pulley 25, as two metallic belt 27.  Each of belts 45, 47 can thereby make curvilinear motion at the same angular speed.

Title: Noise filter
Inventor: HAYASHI KUNIHIRO
IPC: H03H7/01
Filed: 1984-09-21
Abstract: PURPOSE:To prevent leakage of noise possible for causing radio interference while eliminating unnecessary resonance by connecting a resonance suppressing resistor in series between a line bypass capacitor and ground. CONSTITUTION:The resonance suppressing resistor 9 is connected between a connecting point 7 of line bypass capacitors 6, 6 and grounding line 8. The inductance of choke coils 2, 2 and the capacitance of the capacitors 6, 6 cause the resonance, which is attenuated by the resistor 9. Thus, unnecessary resonance is suppressed to prevent noise generation. Since the unnecesary resonance is suppressed in this way, the leakage of noise possible for causing radio interference is prevented.

Title: Vc connection switching system
Inventor: IWATA HIDEAKI
IPC: H04L12/28
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration in communication quality accompanying switching by resetting the reception processing of one protocol in an AAL type at the time of VC connection switching and stopping the transmission of time cells sufficient for re-absorbing delay fluctuation. SOLUTION: When a controller 3 receives the switching request of connection from a terminal 5a, the contents of the header conversion tables of header conversion parts 2a and 2b are set to invalid values having no specified destination and the connection of VC(virtual channel) connection VCab is turned off by using control lines 6a to 6c. The header conversion tables of the conversion parts 2a and 2c are rewritten after prescribed time passes, and CC connection is switched from Vab to Vac . Since the cell is not received in a decell device 4a during a guard time period, a quality monitoring part 7 detects that the reception buffer finder flow of more than a prescribed condition is generated and resets the decell device 4a. Thus, Vac is established and the cell transmitted from a terminal 5c through Vac arrives at the decell device 4a.

Abstract: PURPOSE:To decrease the installing time by providing a storage means deciding antenna adjustment information to a reference satellite as a reference value and storing the antenna adjustment information of other satellites as a quantity deviated from the said reference value. CONSTITUTION:For example, a statellite SAT1 is used as a reference satellite, an antenna adjusting signal from a standard indoor unit 20 is sent to an antenna to decide the antenna optimum azimuth.

IPC: H02M1/34
Filed: 1988-08-10
Abstract: PURPOSE:To control a switching element over a wide range by generating a pulse signal corresponding to the controlled variable of said switching element and by judging through a pulse width judging means whether the ON-pulse width of said signal is more than its minimum value, and by keeping said ON- pulse width at its minimum value. CONSTITUTION:The ON-time Don and period DT of a pulse signal corresponding to the controlled variable for a switching element is inputted from a pulse-signal generator means to a clock control circuit. A pulse signal control means is formed by an arithmetic circuit 21, selector circuits 23-24, a clock generator circuit 25, and pulse generator 26. Said arithmetic circuit 21 outputs arithmetic results Dn by the period DT of said pulse signal to said selector circuits 23-24. Also, a comparator circuit 22 forming a pulse-width judging means outputs a control signal (a) compared for the minimum ON-time to the selector circuits 23-24. Thus, when the control for decreasing the ON-time of said element is performed, the ON-pulse width of a generated pulse signal shortens so that said element can be controlled even by a small controlled variable.

Title: Emulation method for computer system
Inventor: KOMATSU HIDEAKI
IPC: G06F9/455
Filed: 1992-07-27
Abstract: PURPOSE: To optimize emulation of memory access to increase the entire emulation speed. CONSTITUTION: Based on a conventional technique where an attribute table corresponding to one byte of a memory is provided to increase the speed, it is noticed that almost all memory operations are used for data load/store, and almost all memory operation instructions are executed without testing attribute values. The memory space is divided into segments having a certain size, and one segment prediction bit which expresses OR of attribute values of each segment is generated, and OR between the prediction bit of a pertinent segment and those of two adjacent segments is operated. This operation is executed for all of the memory space to generate a segment prediction table. Values '0' of prediction bits stored in this table mean that any memory belonging to segments corresponding to these prediction bits is used for normal memory and the test of each attribute is unnecessary.
